This post is going to focus on a particular aspect of who Jesus is. Usually Christians refer to Jesus as the Son of God, Lamb of God, Saviour, and all of that is true. But for this post I want to focus on the concept of the Logos.

The book of John starts off with " In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning.Through him all things were made; without him nothing was made that has been made. In him was life, and that life was the light of men. The light shines in the darkness, but the darkness has not understood it. (NIV)

The word "Word" in the Greek is logos. It means things like the following (from Strong's Concordance ):

a word, uttered by a living voice, embodies a conception or idea

the act of speaking, a continuous speaking discourse - instruction

reason, the mental faculty of thinking, meditating, reasoning

answer or explanation in reference to judgment

with whom as judge we stand in relation

Now it gets interesting. Logos was first used by a Greek philosopher named
Heraclitus around 600 B.C. to "designate the divine reason or plan which coordinates a changing universe." (Strong's Concordance from Logos Software)

It is that divine reason or plan which coordinates this changing (or dynamic) universe that became flesh on this earth. The living expression (voice) of God that contains the logic or ongoing purpose of this universe, and that created all things, became a part of the universe. That is who Jesus is.
